The fiddle emerged in 10th century Europe. It was not around for the burning of Rome in 64 C.E. Neither was Nero, for that matter. According to the writings of the historian Tacitus, Nero was 30 miles outside Rome in his villa in Antium at the time the fire started.
Nero had previously made it known that he wanted Rome redesigned. He didn’t like the condition the city was in and yet he was powerless to take any action—until it burned. His political allies could’ve started the fires so he’d have his way or his foes could’ve started them so Nero would be blamed. Alternatively, the fire could’ve been a complete accident. Whichever was true, we have all heard the stories of Nero burning Rome or that Nero fiddled while Rome burned.
It doesn’t matter that Nero rushed to help extinguish the fire, paid for relief efforts from his own funds or beautifully rebuilt the city. Nero was a bully and a villain and history has remembered him as such.
It’s not necessary to start the fire or pull the trigger to be the villain; you only need to be persuasive enough that someone else will do those things for you. When a person covers a map in “surveyor marks” and change happens on that map to match his or her political desires, time does not and should not absolve that person of responsibility.
History does repeat itself; some people are, apparently, just too stupid to learn from it.
